Abstract
A method for manufacturing a synthetic image device includes providing of a focusing element array. An image layer is arranged in a vicinity of a focal distance of focusing elements, whereby a synthetic image composed of enlarged portions of the image layer becomes perceivable for a viewer. The image layer includes an array of image cells, each associated with a respective focusing element. The step of arranging the image layer includes creation of a respective image object within each respective one of said image cells. The image objects are such that an animation becomes perceivable, comprising a series of synthetic images perceivable in-series as the viewing direction changes. The image objects are such that each one of the synthetic images of the series is perceivable at a respective perceivable depth, changing between the synthetic images of the series of synthetic images.
